Systems, methods, devices, and computer program products are described for adaptive clustering. Serving cells may receive measurement information from mobile devices, and may each form reporting sets including measurement information for various cells. A CoMP (coordinated multi-point) control unit may receive the measurement information from each of a number of serving cells. The received measurement information may be aggregated for a population of the mobile devices. Based on the aggregated measurement information, cell clusters may be formed to perform coordinated transmissions, each including a different subset of the cells. An indication of the determined cell clusters may be transmitted to respective cells.

A method, a computer program product and a device for requesting access to a node (BS) of a wireless communications network (10) are described. In the network (10) identification codes are used to differentiate access requests of different network components (UE). The method comprises the step of determining information about a transmission path (12) to e.g. the network node (BS), the step of determining an identification code in dependence on the determined transmission path information, wherein previously an association between identification codes and transmission path information has been established, and the step of modulating the selected identification code onto a signal to generate an access request signal carrying transmission path information.

The invention relates to a method, a device and a system for adapting a communications link based on a quality estimate for a signal transmitted via the communications link. The method comprises receiving and demodulating the transmitted signal, assessing the demodulated signal to derive a first estimate for the signal quality that is to be utilized in a link adaptation scheme, and further processing and decoding the demodulated signal, wherein based on at least one of the further processed, non-decoded signal and information obtained prior to conclusion of decoding a first control signal indicative of the signal quality is generated and utilized to control the link adaptation scheme.

The invention relates to a method, a computer program product and a device for evaluating a code which is orthogonal to one or more further codes. The method comprises the steps of receiving a signal which carries a code containing a sequence of code symbols, determining for a particular symbol instant at least one channel estimate, determining for the particular symbol instant a compensation value taking into account the at least one channel estimate, compensating each code symbol using the compensation value determined for the corresponding symbol instant, wherein the compensation is performed such that an original power relationship among the individual code symbols contained in the code is restored, and evaluating the code on the basis of the sequence of compensated code symbols exploiting the orthogonality to further codes.
摘要:
A system and method for detecting and selecting peaks in a delay power profile (DPP) signal. An adaptive threshold is used to determine valid paths in the DPP signal. The adaptive threshold is determined by measuring the signal-to-noise ratio of the DPP signal, and setting the threshold to minimize non-detections and false alarms in path estimation. To determine the signal-to-noise ratio, the system uses an iterative process wherein a raw estimate and an improved estimate are made of the noise.
